Pulled from season 5's first teaser, the premiere title hints at the major changes that will take place as Earth prepares to end the Espheni invasion once and for all.

"A man walks through his life, he stumbles and he falls," Tom Mason (Noah Wyle) explained in TNT's first teaser. "At times he thinks he cannot get up. But he does. Over and over, until one day when a man cannot hold up the sky, falling all around him, anymore and he reaches his journey's end. But there is one last fight, and nothing will be as it was."
